While significant attention has been paid to the possibility of U.S. Sen. Bob Corker being named to Donald Trump's administration, speculation has been growing that U.S. Rep. Marsha Blackburn could be in line for a Cabinet post as well.

After being named last week to Trump's transition team, which also includes ex-Speaker of the House Newt Gingrich and former New York City Mayor Rudy Giuliani, some believe Blackburn could be offered a spot in the administration.

The Brentwood Republican serves as vice chair of the House Energy and Commerce Committee, making a Secretary of Commerce appointment logical. Blackburn also serves as chairman of the House Select Investigative Panel on Infant Lives.

Corker said he believes she's developed a good relationship with the Trump campaign.

“I do know that she’s served for a long time and has a lot of knowledge about any number of areas," Corker said. “My guess is, should she wish to serve in that type of capacity, there might be several options that could well become available for her.”

Unlike the replacement process for a vacant U.S. Senate seat - where Gov. Bill Haslam would get to select who would fill the spot - a vacancy in Tennessee's congressional delegation would require a special election.

State law requires a primary election to occur between 55 and 60 days after the governor orders a special election to fill the vacancy. A general election would be held between 100 and 107 days after the governor's order.

That would mean if Trump were to make his appointments in next week, as some expect, and Blackburn were to be selected, a special primary election could be held as early as January, with the general election sometime in March.

Adam Ghassemi, a spokesman for Secretary of State Tre Hargett's office, said because state and federal law require ballots to be transmitted to military and overseas voters 45 days before an election, the deadlines could be extended.

Tennessee's last special election to fill a congressional vacancy occurred in November 1988, when then-U.S. Rep. John Duncan Sr. died. His son, John Duncan Jr., has held the office ever since.

The vacancy left by Duncan's death was the second in less than a year. In September 1987, then-U.S. Rep. Bill Boner was forced to exit his seat after being elected Nashville mayor. In January 1988, Bob Clement, who was the son of Gov. Frank Clement, was elected to fill the vacancy.

Given the speculation surrounding Blackburn, the conversation among Tennessee Republicans has led to discussions about her possible replacement.

While there is no requirement that a member of Congress live in the district they represent, it would be likely be difficult for a potential candidate to reside outside the 7th District.

Among those being mentioned are Johnson, House Republican Caucus Chairman Glen Casada, R-Franklin, Franklin Republican donor Bill Lee, Clarksville state Senator Mark Green - who is considering running for governor and is in the midst of a statewide listening tour - and Andy Ogles, head of the Tennessee chapter for Americans for Prosperity, a conservative advocacy organization.

Johnson said he hadn't given the idea of running for Congress much thought, adding that he remains focused on the upcoming legislative session. Casada said he was not interested in running "at this moment" should Blackburn's seat become vacant.
